In order to avoid ambiguity and facilitate understanding of the technical scheme, firstly, the direction appearing in the text and the measurement parameters based on the direction are defined, and the front direction refers to the direction of the head of the zipper head, namely the direction of the movement of the zipper head when the zipper belts are combined; "rear" means the direction of the tail of the slider, i.e. the direction of the slider moving when the fastener tape is separated; "above" means a direction toward the outside perpendicular to the surface of the integrated chain, wherein the "outside" is understood to be a side exposed to the outside for the movement of a human hand or the like; "lower" means a direction perpendicular to the merged chain belt surface toward the inside, "length" means a distance in the front-rear direction, "width" means a distance perpendicular to the front-rear direction at the chain belt surface, that is, a distance in the left-right direction.

The invention provides a self-locking pull head, which comprises a pull head body 1, a pull head cover and a pull head cover, wherein the pull head body 1 is provided with a clamping groove 11 and is used for combining and separating two rows of chain belts; the elastic sheet 2 is arranged on the puller body 1 and is used for being clamped and embedded in the gaps of the teeth of the chain belts; the locking block 3 is connected with the elastic sheet 2, is provided with a hook 31 and is used for pressing the elastic sheet 2 when the hook 31 is clamped in the clamping groove 11 and enabling the elastic sheet 2 to deform so as to be clamped and embedded in the gap of the zipper teeth; a cap 4 connected with the slider body 1 and used for pushing the locking block 3 to allow the hook 31 to be clamped in the clamping groove 11; when pressing down cap 4, cap 4 promotes locking block 3 downstream, to pothook 31 joint in draw-in groove 11 of pull head body 1, make locking block 3's fixed position, at the in-process of locking block 3 downstream, locking block 3 pushes down shell fragment 2, make shell fragment 2 take place to deform and downwardly extending to the chain tooth space, in order to block pull head body 1 along the chain belt motion, because locking block 3 joint all the time in draw-in groove 11, therefore shell fragment 2 is compressed always and is deformed and inlay card all the time in the chain tooth space, in order to reach the purpose of locking pull head position.

In this context, the term "element space" refers to a space between two adjacent elements on the same row of the chain belt; the elastic sheet 2 is arranged on the puller body 1 through a channel extending downwards in the upper wing plate support 14; the locking block 3 is arranged in a channel extending downwards in an upper wing plate support 14 of the slider body 1, wherein the locking block 3 is positioned above the elastic sheet 2.

As shown in fig. 3 and 4, the cap 4 is engaged with the upper wing plate support 14 in a wrapping manner, specifically, a groove 12 recessed toward the middle is formed in the bottom of the outer surface of the upper wing plate support 14 along the front-rear direction, and a flange structure 41 extending toward the middle is formed in the bottom of the cap 4 along the front-rear direction, wherein the flange structure 41 of the cap 4 is formed in the groove 12 of the upper wing plate support, so that the cap 4 can move up and down in the groove 12, and the flange structure 41 is blocked by the groove wall of the groove 12 to limit the moving stroke of the cap 4 and prevent the cap 4 from being separated from the slider body 1.

It should be noted that the width of the flange structure 41 is preferably the same as the width of the groove 12 to avoid the cap 4 from shaking and making a sound along the width direction thereof, wherein the width of the groove 12 is determined according to the actual width of the upper flap support 14, and of course, the width of the lower surface of the cap 4 may be set to be the same as the width of the upper flap support 14 to avoid the cap 4 from shaking and making a sound along the width direction thereof; the lower surface of the cap 4 is preferably of the same length as the overall length of the upper flap support 14, on the one hand to avoid rattling and rattling of the cap 4 along its length (i.e. in the front-rear direction), and on the other hand the flange structure 41 is in interference fit with the upper flap support 14 before entering the recess 12, thereby avoiding detachment of the cap 4 from the slider body 1.

As shown in fig. 5 and 6, the cross section of the locking block 3 is wedge-shaped with an arc bottom, and the cap 4 is further provided with a first supporting surface 42 for supporting the top of the locking block 3, pushing the locking block to move downward and press against the elastic sheet 2, so that the elastic sheet 2 deforms, supporting the top of the locking block 3, pushing the locking block to slide along the upper surface of the elastic sheet 2, and allowing the hook 31 to be clamped in the clamping groove 11; when the cap 4 is pressed downwards, the first supporting surface 42 of the cap 4 supports and pushes the locking block 3 to move downwards, and under the influence of the wedge-shaped structure of the locking block 3, the locking block 3 can slide along the upper surface of the elastic sheet 2, when the hook 31 is embedded in the slot 11, the pressure pressed on the cap 4 is removed, because the bottom of the locking block 3 is arc-shaped, the locking block 3 is overturned by taking the hook 31 as a fulcrum and moves to a state that the front surface of the locking block 3 is in contact with the front surface of the channel in the upper wing plate support 14, and finally the position of the locking block is kept unchanged, and the elastic sheet 2 is always kept in a pressed and deformed state, namely the elastic sheet 2 is always embedded in the gap of the zipper teeth.

It should be noted that the width of the locking block 3 is preferably approximately equal to the width of the channel in the upper flap support 14, that is, a certain gap is left between the locking block 3 and the channel in the upper flap support 14 along the width direction, so as to avoid the locking block 3 from moving up and down.

In the first embodiment, as shown in fig. 3 and 6 to 8, the hook 31 is disposed at the bottom of the locking block 3 and at the side close to the front, for manufacturing convenience, the slot 11 is disposed on the plane where the bottom of the upper wing plate support 14 is located, that is, the bottom of the front surface of the upper wing plate support 14 is provided with a through slot penetrating to the inner channel thereof to form the slot 11 for snap-fitting with the hook 31, specifically, when the cap 4 pushes the locking block 3 until the hook 31 contacts the slot 11, the pressure on the cap 4 is removed, the locking block 3 rotates clockwise with the hook 31 as the fulcrum according to the view of fig. 7 until the front surface of the locking block 3 contacts the front surface of the inner channel of the upper wing plate support 14, so as to complete the process of the hook 31 being snapped into the slot 11 and fix the position of the locking block 3, that the upward elastic force exerted on the locking block 3 by the elastic sheet 2 does not push the locking block 3 to move, and the elastic sheet 2 is always pressed to deform and is embedded in the gap of the zipper teeth.

It is conceivable that the hook 31 is preferably provided integrally with the locking block 3, and for convenience of manufacture, the width of the hook 31 preferably coincides with the width of the locking block 3, but of course, the hook 31 and the locking block 3 may be assembled, and the assembly of the two is not particularly limited herein as long as the hook 31 and the locking block 3 can be integrally connected; the hook 31 may also be disposed at other positions of the locking block 3, for example, at a side of the bottom of the locking block 3 near the rear, and the position of the engaging groove 11 of the slider body 1 is also set correspondingly according to the position of the hook 31, and the specific engaging manner is the same as that of the first embodiment, and will not be described herein again.

In order to unlock the slider, as shown in fig. 6, the cap 4 is further provided with a second supporting surface 43 for supporting the top of the locking block 3 and pushing it to move downward and slide backward along the upper surface of the elastic sheet 2, so that the hook 31 can be disengaged from the slot 11.

In a second embodiment, as shown in fig. 7 to 8, based on the first embodiment, the second supporting surface 43 is disposed in front of the first supporting surface 42, when the cap 4 is pressed, the second supporting surface 43 supports and pushes the locking block 3 to move downward, and under the influence of the arc shape at the bottom of the locking block 3, the locking block 3 will slide backward along the upper surface of the elastic sheet 2, and the hook 31 is disengaged from the slot 11, then the pressure on the cap 4 is removed, the locking block 3 will turn counterclockwise according to the view angle of fig. 7 until the rear surface of the locking block 3 contacts with the rear surface of the channel in the upper wing plate support 14, and the elastic sheet 2 will push the locking block 3 to move upward, at this time, the elastic sheet 2 will disengage from the tooth space, and the zipper tapes can be combined and separated without hindrance.

It should be noted that, since the locking block 3 is located relatively downward when the hook 31 is engaged with the slot 11, the height of the second supporting surface 43 should be greater than that of the first supporting surface 42; the position of the second supporting surface 43 depends on the position of the hook 31, for example, if the hook 31 is provided on the rearward side of the locking block 3, the second supporting surface 43 is provided rearward of the first supporting surface 42; for the convenience of manufacturing the cap 4, the portion between the first support surface 42 and the second support surface 43 is preferably configured as a trapezoid structure, but of course, other shape structures which do not affect the turning of the locking block 3 and are convenient to manufacture are also within the protection scope of the present invention.

As shown in fig. 3 to 5, the cap 4 is further provided with positioning structures 44 extending inward on the left and right sides between the first supporting surface 42 and the second supporting surface 43, the upper wing plate support 14 is provided with through slots on the left and right sides of the middle portion thereof, the upper wing plate support 14 is divided into a front portion and a rear portion, and the two positioning structures 44 are disposed in the through slots of the upper wing plate support 14, so as to facilitate the passage of the locking block 3 in the upper wing plate support 14, and further limit the freedom of movement of the cap 4, that is, prevent the cap 4 from swaying in the front-rear direction of the upper wing plate support 14.

In order to alleviate the pain of fingers caused by pressing the cap 4, the cap 4 is further provided with a pressing pad for increasing the force bearing area and/or increasing the flexibility, and the pressing pad can be provided with logo patterns and other decorations to enhance the aesthetic effect.

As shown in fig. 3 and 7 to 9, the elastic piece 2 includes: a fastener-engaging portion 23 having a first end for engaging with the fastener element space; a support portion 22 having a first end connected to a second end of the catching portion 23 for supporting the locking block 3; a resilient part 21 having a first end connected to a second end of the support part 22 for providing elastic force to the support part 22; the puller body 1 is also provided with a step seat 13 which is provided with an upper step surface and a lower step surface and used for placing the elastic sheet 2, wherein the step seat 13 is arranged at the bottom of a channel in the upper wing plate support 14, and a gap is reserved between the step seat 13 and the puller body 1; the springback part 21 is arranged on the lower step surface of the step seat 13, the support part 22 is arranged on the upper step surface of the step seat 13, and the clamping and embedding part 23 penetrates through the gap between the upper step surface and the slider body 1 to clamp and embed the element gap in the slider body 1; specifically, the locking block 3 presses down the supporting portion 22 and slides on the upper surface of the supporting portion 22, and the supporting portion 22 deforms after being pressed, so that the engaging portion 23 moves downward to the gap between the fastener elements, and presses down the resilient portion 21 to generate a resilient force for rebounding the locking block 3 to its initial position when unlocking is performed, where the "initial position" is defined as a position where the locking block 3 is not engaged with the engaging slot 11 and is not subjected to other external forces.

Preferably, as shown in fig. 9 and 10, the resilient portion 21 is curved to provide a resilient force to the support portion 22, and specifically, as shown in fig. 7 to 8, the resilient portion 21 extends forward and then extends backward, and a portion of the resilient portion extending backward is disposed on an upper step surface of the step seat 13, when the resilient portion 21 is pressed by the deformation of the support portion 22, the portion of the resilient portion extending forward moves downward, and a resilient force in an upward direction is generated between the portion of the resilient portion 21 extending backward and is transmitted to the support portion 22 through the portion of the resilient portion extending forward; of course, the resilient portion 21 may be other members capable of providing resilient force to the supporting portion 22, such as a spring.

In the case of a symmetrical aesthetic, as shown in fig. 1 and 2, the cap 4, the locking piece 3, and the elastic piece 2 are provided at the center of the slider body 1 in the left-right direction, but the cap 4, the locking piece 3, and the elastic piece 2 may be provided at other positions such as a side of the slider body 1 closer to a row of fastener tapes connected thereto all the time.

It can be understood that, if the elastic sheet 2 is disposed at the central position, since the teeth of the two rows of fastener tapes are staggered, the engaging portion 23 of the elastic sheet 2 should be engaged with only the teeth gap of one row of the teeth, and further, the width and position of the end of the engaging portion 23 should be sufficient to be engaged with only the teeth gap of one row of the fastener tapes, preferably, as shown in fig. 10, the end of the engaging portion 23 should be retracted toward one side of the fastener tape connected to the slider body 1 at all times, and of course, the end of the engaging portion 23 may be retracted toward the other side; in addition, if the spring plate 2 is disposed at a position other than the central position, the end of the engaging portion 23 is preferably inclined toward the direction of the position of the spring plate 2, and it is within the scope of the present invention to satisfy that the engaging portion 23 is engaged with only the element gap of a row of elements.

The above-mentioned "one row of fastener tapes always connected to the slider body 1" is specifically the one row of fastener tapes from which the slider body 1 is still suspended when two rows of fastener tapes are separated.

In the third embodiment, as shown in fig. 11, in order to realize the one-way locking of the slider, that is, the slider can still combine the fastener tapes after being locked, the front surface (that is, the lower surface) of the end of the above-mentioned engaging portion 23 is provided with a buffer sub-portion 231 whose width is reduced along the end direction, when the engaging portion 23 is engaged with the fastener element gap, if the slider is pushed to move forward in the fastener tape, the engaging portion 23 is deformed by swinging upward, and the inclined surface of the buffer sub-portion 231 can provide a certain buffer for the movement of the slider; if the slider is pushed to move backward on the fastener tape, the engaging portion 23 is deformed to swing downward and abuts against the upper step surface of the step base 13, so as to prevent the slider from separating the fastener tape.

In the fourth embodiment, as shown in fig. 12, in order to realize bidirectional locking of the slider, that is, the slider can neither merge nor separate the fastener tapes after being locked, the front surface (i.e., the lower surface) of the end of the above-mentioned engaging portion 23 is provided with a locking sub-portion 232 whose width increases along the end direction, when the engaging portion 23 is engaged with the fastener element gap, if the slider is pushed to move forward in the fastener tape, the engaging portion 23 has a tendency of upward swinging deformation, but the locking sub-portion 232 will clamp the fastener elements to block the slider from moving forward to merge the fastener tapes; if the slider and the fastener tape are pushed to move backward, the detailed process can refer to the third embodiment, and the detailed description is omitted here.

Of course, in order to simplify the processing process of the elastic sheet 2, the embedding part 23 in the fourth embodiment can be made of rigid material, and the locking sub-part 232 is not required to be arranged, when the slider has a tendency to move along the fastener tape (to open or separate the fastener tape), the rigid embedding part 23 is not deformed to block the movement tendency of the slider, and the bidirectional locking of the slider is realized.
